Rob Gronkowski broke his left forearm back in November, and had surgery to fix it. He returned for Week 17, played sparingly, then broke his left forearm in the Patriots' first playoff game. It's easy enough to jump to the conclusion that he came back too soon, that he wasn't completely healed up yet. But the reality is both better and worse for him and the Patriots—his arm was as durable as it's ever going to be, but might never be 100 percent again.

"If he heals it, it's one thing, but he has to actually have the strength to tolerate the amount of impact that these guys tolerate on a play-to-play basis," said Forsh. "(Healing) sometimes takes a little more time for a bone to develop its strength again to retake that impact. . . . On an X-ray you look at it and say, ‘Oh, the bone is healed.' That may or may not necessarily say that he can tolerate the load that he sustained during a simple fall like that."

Well, Gronkowski had another surgery yesterday, and it was discovered that the second break is in a completely different place than the first—that it wasn't a reaggravation of the initial injury. According to CSN New England, the new fracture—sustained when Gronkowski awkwardly broke his fall with the arm—"had nothing to do with whether the arm was ready or not." That absolves the Patriots and their medical staff of any blame.

The CSN report goes a bit further, though, and this is the disheartening part. The arm broke at the end of the protective metal plate installed in Gronkowski's arm. This isn't a coincidence—the plate "funnels" stresses to the ends, leaving those areas more susceptible to future fractures. As long as Gronk has that plate, he'll be at risk of more breaks. Depending on the injury, some plates are left in for a year or two, and some remain forever. Two fractures in two months mean Gronkowski's going to be very aware of what he does with that left arm going forward.
